High surface nanosized rutile TiO2 is prepared via a sol-gel method from an ethylene glycol-based titanium-precursor in the presence of a non-ionic surfactant, at pH 0. Its electrochemical behaviour has been investigated at low temperature using two different potential windows. Typically, the potential window of the rutile system is 1-3 V but the use of an enlarged potential window (0.1-3 V), leads to an excellent reversible capacity of 341 mAh g-1 which is comparable to graphite anodes. The electrochemical performance was investigated by cyclic voltammetry and galvanostatic techniques at temperatures ranging from -40 to 20 °C. Nanosized TiO2 exhibits excellent rate capability (341 mAh g -1 at 20 °C, 197 mAh g-1 at -10 °C, 138 mAh g -1 at -20 °C, and 77 mAh g-1 at -40 °C at a C/5 rate) and good cycling stability. The superior low-temperature electrochemical performance of nanosized rutile TiO2 may make it a promising candidate as lithium-ion battery material.
